graph.par(...)
graph.par.get(name)graph.par
returns a list containing the current values of the requested
parameters. When called with no arguments, it returns a list with all
parameters. When a parameter is set, the return value is a list
containing previous values of these parameters.graph.par works sort of like par, but the details
are yet to be decided. graph.par.get(name) is equivalent to graph.par(name)[[1]]
